I recently heard an example of an effect I'd really like to learn how to reproduce. It's like a combination of a fade out and echo/reverb used to link from one bit of audio to another, e.g. in a radio bumper. You can hear the example I heard here: https://overcast.fm/+FrasInw/14:54 (that's at minute 14 and 54 seconds, in case the timestamp link doesn't work)

Can anyone tell me what this is called and whether it's practical to achieve it in Audacity, where I do most of my editing?

Thanks in advance! James

I presume you're referring to that part at the end of the Sister Sledge clip, where the final lyric "Sing" is reverb faded out.

To achieve something like this in Audacity, you'd first need to sample a portion of the song that you'd like to use, taking into account extra room for any fade-in and fade-out that you require.

To add the reverb effect, you'd select/highlight only the final part of the clip where you hear the lyric 'Sing' and apply reverb to that. Trying previewing with different amounts of Dry/Wet mix (so it doesn't get exaggeratedly louder/quieter). Also make sure you adjust the length of the reverb time so you can apply a good fade out. Then apply the reverb effect, your clip should increase in length due to the reverb.

Sometimes the reverb will fade-out exactly how you want, or you can apply a volume fade-out to the end of the clip to make it happen sooner if required.

That's pretty much all there is to it, you just need to practice playing with the reverb controls to get the desired effect, that just comes with experience.

  • Whoops, I copied the wrong timestamp link! You're absolutely right, that's the part I was referring to. Thanks for persevering; I'll give this a try later!

    Got it! In Audacity at least the key thing was to select the sample and a good amount of silent time after, which Audacity uses to control the length of the fade. Sounds like the authors of that clip also removed a drum hit on the "sing!", but that's an exercise for another time :). Thanks again!
